Hi Everyone,

I am running Ubuntu 20.04.4 x86_64 fully patched. I installed
VirtualBox 6.1 through Synaptic. I have a Windows 10 guest in
VirtualBox.

The application I am testing in the guest is not seeing some CPU
features. In particular, SHA is being masked out by VirtualBox. (AES,
RDRAND, RDSEED and PCLMULQDQ are present, however).

How do I tell VirtualBox to make all CPU features available to the guest?

Thanks in advance.
